%X With seismic evaluation in the construction of Ji'nan subway as research background, dynamic triaxial tests of typical soils are carried out and the test results are statistically analyzed. Results imply that, in the same soil layer, with the increase of shear strain, dynamic shear modulus ratio decreases, whereas damping ratio increases. However, the test data is discrete. Dynamic constitutive model of soil is of good effect in fitting the test results. Compared with research results in other areas, the dynamic shear modulus ratio of soils in Ji'nan City is large, while damping ratio is small, indicating that the dynamic properties of soils in Ji'nan is favorable for earthquake resistance. This study not only helps to understand the dynamic properties of soils in Ji'nan, and also provides reference for engineering seismic design.
